Expected Student Behavior



Procedure for Communicating and Resolving Student Concerns


A student who has a grievance concerning an academic course in which he or she is enrolled should make an appeal in the following order to the:

1. Instructor.
2. Department Chair/Program Director.
3. Dean.
4. Vice President of Academic Affairs.
5. College President.


The purpose of this policy is to secure at the first possible level prompt and equitable resolution of student complaints, including those alleging discrimination on the basis of race, religion, color, sex, national origin, age, or disability.

The student may be represented at any level of the complaint.

Discrimination Complaints
Any student who believes that he or she has been discriminated against on the basis of race, religion, color, national origin, sex, age, or disability by the institution or its personnel may informally discuss the complaint with the Associate Vice President of Student Affairs with the objective of reaching a reasonable solution. The Associate Vice President of Student Affairs shall advise the student of his or her options in the situation and notify the Director of Administrative Services/Human Resources of the College.

If the aggrieved student believes the complaint has not been resolved at the informal discussion, he or she may submit a written complaint stating his or her name, the nature and date of the alleged violation, names of persons responsible (where known), names of any witnesses, and requested action within 30 working days of the date of the informal discussion, to the Vice President of Student Affairs. The Associate Vice President of Student Affairs shall ensure that the aggrieved student’s rights to appropriate due process procedures are honored. If a hearing is held, the Vice President of Student Affairs and the Associate Vice President of Student Affairs shall conduct the hearing. The Vice President of Student Affairs and the Associate Vice President of Student Affairs will consult with the College legal counsel and render a decision in writing on the complaint within ten working days. If this decision is not to the student’s satisfaction, he or she may appeal the decision to the Vice President of Student Affairs within ten working days of the receipt of the written decision according to procedures at Level Two below.


Level One
A student who has a complaint may either request a conference with the Associate Vice President of Student Affairs or submit the complaint in writing. Written complaints may be initiated at the following location:

Level Two
If the outcome of the conference with the Associate Vice President of Student Affairs is not to the student’s satisfaction, the student has 15 calendar days to request a conference with the academic division chair or Vice President of Student Affairs, as appropriate, or designee(s), who shall schedule and hold a conference. Prior to or at the conference, the student shall submit a written complaint that includes a statement of the complaint and any evidence or witnesses in its support, the solution sought, the student’s signature, and the date of the conference with the division chair or Associate Vice President of Student Affairs.

Level Three
If the outcome of the conference at Level Two is not to the student’s satisfaction, the student has 15 calendar days to request a conference with the College President or designee, who shall schedule and hold a conference. Prior to or at the conference, the student shall submit the written statements required at Level Two and the date of the conference with the Vice President of Student Affairs.

After exhausting Amarillo College’s grievance/complaint process, current, former, and prospective students may initiate a complaint with The Texas Higher Education Coordinating Board. Directions are available at the following location:


Each student will be required to prepare written assignments for credit and take written examinations as a part of this course. PLAGIARISM, ACADEMIC DISHONESTY OR ANY OTHER UNETHICAL CONDUCT WILL NOT BE TOLERATED. Such behavior may result in the student receiving a final course grade of “F” regardless of the other grades earned in class to-date.  One should conclude that any unethical conduct is absolutely prohibited by Amarillo College policy.  To be more specific, plagiarism, cheating, falsifying competency records, or any other unethical conduct, will be cause for a final course grade of “F”, or even dismissal from the program without the ability to re-enroll at some later date. 
Electronic devices that produce audible sounds must be deactivated in the classroom during class. This includes but is not limited to cellular telephones, pagers, and watches. Electronic devices will not be a distraction during lecture time (you cannot effectively listen and participate in class and utilize your phone or other device). Instructor reserves the right to have electronic devices placed in a common area at any time during the lecture and/or review time.

Grading Criteria

The course grade will be computed as follows:

Average of Unit/Chapter Examinations/Modality Paper = 40%

Average of quizzes/graded assignments = 20%

Final Comprehensive Examination = 40%


The following grade scale shall apply during this course:


A= 91.5-100    

B= 82.5-91.4                  

C= 74.5-82.4      

F= less than 74.5


A grade of “D” is not possible in this course!


You alone are responsible for your final semester grade. The instructor will not round final grades up to increase your letter grade.

There is no extra credit available for this course.  All grades are important, I encourage each student to put forth extra effort from the start of any course.

Non-scheduled assignments/pop quizzes cannot be made up, if missed, a grade of zero will be entered into the grade book. Any/All scheduled assignments/quizzes/exams that are scheduled and not completed in the time or place scheduled can be completed but with only 80% of the original score within the first 24 hours, after 24 hours, a zero will be added into the gradebook. For example, if a quiz is scheduled during an in-class meeting and you are not in class, you can complete, but the 20% reduction will be applied.  You are responsible for turning in your assignment complete and on time by the due date and time.

Unit exams can be made up if a student misses the exam on the scheduled day/time. Timely arrangements will need to be set up by the student to complete the make-up exam within 1-2 school days.  Make-up exams will receive only partial credit of 80%.

*Partial credit refers to 80% of the original maximum point value.

For example, if a student takes a 100-point unit examination at an unscheduled time or late due to an absence. If the score is 90% on the make-up exam, a 72% (90 x.80=72) will be recorded in the grade book.

In the case of extreme circumstances, the instructor will consider elimination of the 20% reduction if prior arrangements have been made with the instructor.

Any scored activity not completed in accordance with these policies shall be scored as ZERO credit and will be averaged as such into the final course grade. 


Modality Paper

RADR 2309 will consist of a written Modality Paper that will count as a unit exam grade in the grade book.

ARRT Prep Exams

Exams will be entered as a quiz grade and will be graded as follows:

0-30 points=F (70 will be entered in the grade book); 31-50 points=C (80 will be entered in the grade book); 51-80 points=B (90 will be entered in the grade book) 81-100 points=A (100 will be entered in the grade book).

Radiography Program Tutoring Policy

Mandatory tutoring (may be in the form of class remediation, post exam worksheets, a personal meeting with the instructor, or other as deemed necessary) is required if a student scores below 75 on a major exam in the course.  It is the responsibility of the student to complete/attend a tutoring session or activity before the next exam.  Students who fail to attend tutoring will not be allowed to take the next test until remediation is done.

Remote Testing Rules

1. During the pre-exam portion, students are required to take a student photo, show valid photo ID, and preform a complete environment scan with the detachable web cam. Any approved blank scratch page or standard calculator (nonscientific) must be shown on pre-exam scan.  After the complete environment scan, you should properly place the detachable web cam. A properly placed web cam should be at about a 45° angle You will also need sufficient lighting during the pre-exam and exam portions and the microphone must be turned on and recording.
A. Approved scratch paper: (1) 8.5 x 11 dry erase sheet that is supplied by the instructor (if you are supplied with the dry erase sheet, that is the method you should utilize) or (2) blank piece of paper (can only be utilized if a dry erase sheet is not supplied by the instructor) that is no larger than 8.5 x 11, if utilizing this type of scratch paper, it must be torn up or cut up in view of the instructor after completing the exam and prior to the video being terminated.
B. Approved calculator: standard nonscientific calculator or the enabled standard calculator in Respondus Lockdown browser.

2. No smart technology allowed in the same room, other than the computer on which you are testing. (no tablets, smart watches, etc). If a calculator is required, you can utilize a basic calculator and have a blank piece of scratch paper that is no larger than 8.5 x 11.

3. You may not leave the room for any reason during the exam, plan accordingly for this.

4. If you are booted off the exam, you may retrieve your phone because you must take a screen shot of what it shows when it boots you off and send it to the instructor immediately.

5. If you are booted off, you must immediately attempt to log back in to the exam.

6. No two students (or more) may test in the same room at the same time. Each student should be alone while testing.

Failure to comply with any of the above rules will result in a 10 point reduction in the test grade for EACH infraction. For example, if you get booted off and wait 30 minutes to log back in (which the instructor can monitor) and you do not take a screen shot and send it to the instructor, that will result in a 20 point reduction of your test grade. If you are sick and think you may need to leave to go to the restroom, do NOT begin the exam. Contact the instructor to work out a different time to take the exam.

Any student who thinks that a penalty was misapplied can request that the penalty be reviewed according to the grievance procedure.


Regular and punctual attendance is necessary for satisfactory achievement. It is the responsibility of the student to attend class. The student is responsible for any missed information from any missed classes.
